Mathematics of Large Eddy Simulation of Turbulent Flows Springer, Berlin

Książki / Literatura obcojęzyczna

Large eddy simulation (LES) is a method of scientific computation seeking to predict the dynamics of organized structures in turbulent flows by approximating local, spatial averages of the flow. Since its birth in 1970, LES has undergone an explosive development and has matured into a highly-developed computational technology. It uses the tools of turbulence theory and the experience gained from practical computation.This book focuses on the mathematical foundations of LES and its models and provides a connection between the powerful tools of applied mathematics, partial differential equations and LES. Thus, it is concerned with fundamental aspects not treated so deeply in the other books in the field, aspects such as well-posedness of the models, their energy balance and the connection to the Leray theory of weak solutions of the Navier-Stokes equations. The authors give a mathematically informed and detailed treatment of an interesting selection of models, focusing on issues connected with understanding and expanding the correctness and universality of LES.This volume offers a useful entry point into the field for PhD students in applied mathematics, computational mathematics and partial differential equations. Non-mathematicians will appreciate it as a reference that introduces them to current tools and advances in the mathematical theory of LES.

Książki / Literatura obcojęzyczna

This volume contains the Proceedings of DLES-5, the fifth international ERCOFTAC workshop on direct and large-eddy simulation which was held at the Munich university of Technology, August 27-29, 2003. It covers all aspects of DNS and LES, but also hybrid methods like RANS/LES coupling and detached-eddy simulations designed to provide answers to technical flow problems at reasonable computational cost. Being organized in four parts, the book covers issues in LES modelling and numerics in its first part, i.e. subgrid-scale modelling, wall models for LES and numerical techniques as well as error estimation. Laminar-turbulent transition phenomena in incompressible and compressible flows form the topic of part 2. Turbulent flows involving complex physical phenomena like multiphase and non-Newtonian effects, scalar transport, combustion, compressibility and noise generation are at the heart of part 3. Turbulent flows in complex geometries bridge the gap in part 4 to practical flow configurations in aerodynamics, turbomachinery and several other applied sciences.

Large-Eddy Simulation of Subsonic and Supersonic Film Cooling Flows Shaker Verlag

Książki / Literatura obcojęzyczna

In this numerical study film cooling flows are analyzed. To be more precise, two categories of flows are investigated each of which undergoes an external pressure gradient. The first is the subsonic flow over the rear part of turbine blades at misaligned flow or over the rear part of high-lift turbine blades and the second problem is the cooling flow in a supersonic combustion ramjet (scramjet). The cooling film interactions are characterized by analyzing the instantaneous flow field, mean flow field, and turbulence statistics. Additionally the simulations are extensively validated by experimental data.

Film Cooling from Inclined Holes VDM Verlag Dr. Müller

Książki / Literatura obcojęzyczna

Film cooling is the mechanism which supplies bleed compressor air from internal convective passages onto the surface of an airfoil in order to protect the surface from excessive heat loads. The resulting flowfield is extremely complex, and the efficiency of a cooling scheme is very sensitive to the details of the geometrical and physical conditions. This book provides a comprehensive computational study of film cooling from inclined cylindrical holes issued into a turbulent boundary layer with a high-fidelity turbulence modeling approach - Large Eddy Simulations. It starts with the details of the numerical methodology developed for the simulations, including its testing and validation. It proceeds with the documentation of the results of the cooling simulations, presents an extensive analysis of the flow physics, thermal properties and cooling efficiency, as well as the detailed comparison with experiments. Engineers and scientists interested in developing computational software for simulating turbulent flows, as well as professionals in gas turbine industry, and anyone interested in heat transfer and fluid dynamics, will find this book a valuable reference.

Environmental Impact of Dams - 2850280495

Environmental Impact of Dams GRIN Verlag

Książki / Literatura obcojęzyczna

Scholarly Essay from the year 2013 in the subject Environmental Sciences, grade: 10.0, Indian Institute of Technology, Delhi, language: English, abstract: According to WWF: Worldwide the total amount of water stored in dams is 3-6 times more than that contained in rivers. The wetlands area during the 20th century has decreased by over 50%. Out of the 10,000 recorded freshwater species more than 20% have either become extinct, threatened or endangered in recent times.§These facts are enough to justify the tremendous impact on environment dams are having. Large scale projects like dams are often floated as important and necessary means of economic development. But this development comes at some or the other cost. Cost to the environment, development and society. So what are dams really for? Water supply for the general public for domestic uses as well as irrigation which is imperative for our agrarian Indian society. Hydroelectric power generation. India is the 7th largest producer of hydroelectric power with 114 Tetra-watt hours. It produces 3.3% of the world total. Dams impede the turbulent and sudden flow of water to prevent floods.§§Well that is what they are for and granted many of them achieve the above given purposes but they are subject to widespread criticism and debate. Several vehement national and international movements have brought into light the severe problems associated with them. Dams have been criticized for disturbing natural water flows, affecting deposits of nutrients as well as lifecycles of species that depend on freshwater habitat. Reductions in water quantities can increase salinity and make the water unusable for drinking and irrigation. The transport of sediments that are crucial for natural cycles is also affected. This may cause flood risks, lower groundwater tables and in turn affect entire ecosystems. With that said we must point out that dams do not always have a negative impact on habitats. E.g. once reservoirs become established they can become sites where birds can thrive. There are cases where dam projects have taken up significant compensation for the environmental damage they had caused during their initial phases, but these cases are few and far between. In this report, we take up the issue of impact of dams from three different perspectives which we believe are best suited for such a topic: - Economics, Population and Risks and Hazards. We first present them individually and give a brief analysis of each perspective then we present a comprehensive and thorough conclusion at the end.
